Abstract

The present application provides a prefabricated rolling welding machine and a method for processing a steel reinforcement cage. In the present application, the main reinforcement bars are arranged through the semi-circular ring-shaped steel bar clamping grooves installed between the slidable support groups, which can ensure that the spacing of the main reinforcement bars is evenly distributed. All the main reinforcement bars are efficiently connected through the prefabricated steel bar auxiliary processing channel steel rings, avoiding manual bar threading, saving time and effort while improving safety. The rotation driving devices at both ends work synchronously to drive the rotating member to rotate, and then drive the steel reinforcement cage connected through the auxiliary processing channel steel ring to rotate, so that the welding construction of the stirrups can be carried out efficiently. Compared with the longitudinal feeding method of the steel reinforcement cage, the floor area is effectively reduced.

[0056] Please refer to Figures 1 to 5 together, and a prefabricated rolling welding machine and a method for processing a steel reinforcement cage provided by an embodiment of the present application will be described.

[0057] In an embodiment of the present application, an assembled rolling welding machine of the embodiment of the present application includes a transverse guide rail group 1, at least two support groups 2, a longitudinal guide rail group 4, two connecting rods 8, two sliding platforms 5, two rotary driving devices 6, at least two semi-circular steel bar clamping grooves 3, at least two auxiliary processing channel steel rings 14, and two rotary members 13. The transverse guide rail group 1 includes at least two laterally spaced guide rails. Each support group 2 includes two symmetrically arranged supports, namely a first support 201 and a second support 202. Two symmetrically arranged supports are slidably connected to each transverse guide rail. The longitudinal guide rail group 4 includes two sets of longitudinally symmetrically arranged guide rails at both ends of the transverse guide rail group 1. Both ends of the transverse guide rail are respectively connected to the connecting rod 8, and the connecting rod 8 can be made of channel steel. Both ends of each sliding platform 5 are respectively slidably connected to the longitudinal guide rails. The two rotary driving devices 6 are respectively arranged on the two sliding platforms 5. One semi-circular steel bar clamping groove 3 is movably connected to each support group 2. A plurality of concave-convex clamping openings 17 for clamping steel bars are spaced on each semi-circular steel bar clamping groove 3. The concave-convex clamping openings 17 can be equally spaced on the semi-circular steel bar clamping groove 3. The concave-convex clamping openings 17 are processed and formed according to parameters such as the spacing of main steel bars. During use, the main steel bars are simply laid on it for welding construction. At least two semi-circular steel bar clamping grooves 3 movably support the auxiliary processing channel steel ring 14. One end of each rotary member 13 is movably connected to the rotating shaft of a rotary driving device 6, and the other end is movably connected to the auxiliary processing channel steel ring 14.

[0058] In an embodiment of the present application, the transverse guide rail group 1 includes three laterally spaced first transverse guide rails 101, second transverse guide rails 102, and third transverse guide rails 103. Two symmetrically arranged supports are slidably connected to each of the first transverse guide rail 101, second transverse guide rail 102, and third transverse guide rail 103. The longitudinal guide rail group 4 includes a first longitudinal guide rail 401 and a second longitudinal guide rail 402. Both ends of the sliding platform 5 are respectively slidably connected to the first longitudinal guide rail 401 and the second longitudinal guide rail 402, as Figure 1 、 Figure 2 shown.

[0059] When an assembled rolling welding machine according to an embodiment of the present application is in use, according to the diameter of the reinforcement cage to be fabricated, two brackets on each transverse guide rail are slid to appropriate positions and then fixed, and two sliding platforms 5 are slid to appropriate positions on the first longitudinal guide rail 401 and the second longitudinal guide rail 402 and then fixed. Then, a rotary drive device 6 is fixedly connected to each sliding platform 5. After that, semi-circular ring-shaped steel bar clamping grooves 3 are fixedly installed on each bracket group 2, and the main reinforcement steel bars to be welded are suspended at the concave-convex clamping openings 17 of each semi-circular ring-shaped steel bar clamping groove 3, and the positions of the main reinforcement steel bars are adjusted so that the ends of the steel bars are on the same horizontal plane. Two auxiliary processing channel steel rings 14 are hoisted to the semi-circular ring-shaped steel bar clamping grooves 3 at both ends, and the main reinforcement steel bars to be welded are welded to the auxiliary processing channel steel rings 14 in sequence, thus completing the welding of half of the main reinforcement steel bars. Then, the auxiliary processing channel steel rings 14 at both ends are synchronously hoisted and rotated 180 degrees, and the above operations are repeated to complete the welding of the other half of the main reinforcement steel bars. Rotary members 13 are respectively connected to the auxiliary processing channel steel rings 14 at both ends, and the rotating shaft of the rotary drive device 6 is connected to the rotary members 13. Then, the rotary drive devices 6 at both ends are synchronously lifted, so that the reinforcement cage is separated from the semi-circular ring-shaped steel bar clamping grooves 3. The end of the stirrup is first welded to a main reinforcement steel bar, and the rotary drive devices 6 at both ends are synchronously started to drive the rotary members 13 at both ends to rotate continuously and uniformly synchronously, so as to wind the stirrup around the main reinforcement steel bar while welding construction is carried out, thereby forming a finished reinforcement cage, and then the stirrup is cut off to complete the manufacturing process of the reinforcement cage.

[0060] Each structural part of the assembled rolling welding machine according to an embodiment of the present application can be assembled into one body through simple assembly, and the structure is relatively simple and the floor area is relatively small. By arranging the rotary drive device 6 on the longitudinal sliding platforms 5 at both ends of the reinforcement cage, the rotary drive device 6 controls the synchronous rotation of both ends of the reinforcement cage, and the rolling welding machine according to an embodiment of the present application can wind the stirrup around the main reinforcement steel bar and carry out welding construction while keeping the reinforcement cage rotating in place. Compared with the way of longitudinal feeding of the reinforcement cage, the floor area is effectively reduced.

[0061] By arranging a plurality of transverse guide rails and slidable bracket groups 2 slidably connected to the transverse guide rails, and cooperating with the auxiliary processing channel steel rings 14 and semi-circular ring-shaped steel bar clamping grooves 3 with different reinforcement cage diameter sizes, the assembled rolling welding machine according to an embodiment of the present application can meet the processing and manufacturing of reinforcement cages with different size requirements, and improves its general applicability.

[0062] The main reinforcement steel bars are connected by the auxiliary processing channel steel rings 14 and semi-circular ring-shaped steel bar clamping grooves 3 in the assembled rolling welding machine according to an embodiment of the present application, avoiding manual steel bar threading, improving production efficiency, saving time and effort and improving safety at the same time.

[0063] In an embodiment of the present application, an assembled rolling welding machine ensures that the spacing between main reinforcement bars is distributed as required to meet the quality control requirements of the steel reinforcement cage by arranging a semi-circular ring-shaped steel bar slot 3 and placing the main reinforcement bars at the concave-convex bayonet 17 of the semi-circular ring-shaped steel bar slot 3.

[0064] In an embodiment of the present application, the rotary drive device 6 includes a lifter 9, a mounting base 10, and a servo motor 11. One end of the lifter 9 is fixed on the sliding platform 5, and the mounting base 10 is connected to the lifter 9; the servo motor 11 is fixed on the mounting base 10, and the rotating shaft of the servo motor 11 is connected to the rotating member 13. The two servo motors 11 at both ends in the embodiment of the present application are driven by a one-to-two servo motor driver 7, and the one-to-two servo motor driver 7 can be fixedly connected to the sliding platform 5. During use, the height of the mounting base 10 is adjusted by adjusting the height of the lifter 9, and then the height of the servo motor 11 fixed thereon is adjusted. When it is necessary to lift the steel reinforcement cage to disengage it from the semi-circular ring-shaped steel bar slot 3, only the height of the lifters 9 at both ends needs to be synchronously increased. After the steel reinforcement cage is fabricated, the height of the lifter 9 can be lowered again to lower the welded steel reinforcement cage onto the semi-circular ring-shaped steel bar slot 3. The lifter 9 in the embodiment of the present application can adopt an electric turbine lifter.

[0065] In an embodiment of the present application, the assembled rolling welding machine further includes support frames 12 provided at both ends of the mounting base 10. The support frames 12 include two symmetrically arranged vertical rods 121, and one end of each vertical rod 121 is fixed on the sliding platform 5. By arranging two vertical rods 121 at both ends of the mounting base 10, the mounting base 10 can always move within the space defined by the two vertical rods 121 during up and down movement, which is beneficial to maintaining the stability of the movement of the mounting base 10.

[0066] Furthermore, the support frames 12 in the embodiment of the present application further include two symmetrically arranged first diagonal braces 122. One end of each first diagonal brace 122 is fixedly connected to the mounting base 10, and the other end abuts against the vertical rod 121, that is, one end of the first diagonal brace 122 contacts but is not connected to the vertical rod 121. By arranging the first diagonal braces 122, auxiliary supporting force is provided to the mounting base 10 to reduce the pressure impact of the mounting base 10 on the lifter 9 below it.

[0067] Furthermore, the support frames 12 in the embodiment of the present application further include two symmetrically arranged second diagonal braces 123. One end of each second diagonal brace 123 is fixedly connected to the sliding platform 5, and the other end is fixedly connected to the vertical rod 121. By arranging the second diagonal braces 123, auxiliary supporting force is provided to the vertical rod 121 to enhance the stability of the support frames 12.

[0068] In an embodiment of the present application, the support includes a vertical column 203, an inner diagonal brace 204, and an outer diagonal brace 205. The inner diagonal brace 204 and the outer diagonal brace 205 are respectively arranged on both sides of the vertical column 203, and the inner diagonal brace 204 and the outer diagonal brace 205 are both inclinedly connected to the vertical column 203, as shown in Figure 1 , Figure 3 , Figure 5 . The lower ends of the vertical column 203, the inner diagonal brace 204, and the outer diagonal brace 205 are all slidably connected to the transverse guide rail. By arranging an inclined inner diagonal brace 204 and an inclined outer diagonal brace 205 on both sides of the vertical column 203 respectively, the support stability of the overall structure of the support can be ensured. In the embodiment of the present application, the upper end of the outer diagonal brace 205 is fixedly connected to the upper end of the vertical column 203, and the upper end of the inner diagonal brace 204 is connected to the middle position of the height of the vertical column 203, which is convenient for making steel reinforcement cages with different cross-sectional sizes by adjusting the position of the support group 2.

[0069] In an embodiment of the present application, the rotating member 13 includes at least two rotating rods of the same length. One end of each rotating rod is connected to the inner wall of the auxiliary processing channel steel ring 14, and the other ends converge and are connected to the center of the auxiliary processing channel steel ring 14. In the embodiment of the present application, the rotating member 13 is composed of six rotating rods, which can rotate around the central servo motor 11. The ends of the rotating rods just contact the inner wall of the steel reinforcement cage auxiliary processing channel steel ring 14. The auxiliary processing channel steel ring 14 is provided with circular holes corresponding to each rotating rod at corresponding positions, and the ends of the rotating rods are detachably connected to the circular holes of the auxiliary processing channel steel ring 14, as shown in Figure 3 , Figure 4 . The auxiliary processing channel steel ring 14 is a prefabricated channel steel ring, and its diameter size is determined according to the size of the steel reinforcement cage to be made. During use, first weld the auxiliary processing channel steel ring 14 to all the main reinforcement bars, and then connect the auxiliary processing channel steel ring 14 to the rotating member 13.

[0070] In an embodiment of the present application, a fixed support plate 16 is provided in the middle of each transverse guide rail, which is used to support the semi-circular steel bar slot 3 placed thereon and the weight of the steel reinforcement cage above it, so as to provide a stable and reliable supporting force for the semi-circular steel bar slot 3 and the steel reinforcement cage.

[0071] In an embodiment of the present application, each support is provided with a fixed clip 18 for fixedly clamping the semi-circular steel bar slot 3. In the embodiment of the present application, the fixed clip 18 is arranged on the inner diagonal brace 204 of the support, as shown in Figure 5As shown, the fixing clip 18 can be two steel plates symmetrically arranged on both sides of the inner diagonal brace 204. The width between the two steel plates is equal to the thickness of the semi-circular ring steel bar slot 3, so that the semi-circular ring steel bar slot 3 can be just stuck into it and fixed. Further, fixing clips 18 can also be arranged on both sides of the fixed support plate 16 on the transverse guide rail close to the semi-circular ring steel bar slot 3. In addition, fixing clips 18 can also be arranged on the upper side of the column 203 close to the semi-circular ring steel bar slot 3 to further fix the position of the semi-circular ring steel bar slot 3 placed between the support groups 2.

[0072] In an embodiment of the present application, the transverse guide rail includes two channel steels with concave surfaces facing each other and a steel plate connected between the two channel steels, as Figure 1 shown. The lower ends of each support group 2 can slide in the middle groove of the transverse guide rail, that is, on the upper surface of the middle steel plate. Further, a plurality of threaded holes are provided on the upper surface of each channel steel along the length direction of the transverse guide rail, and the plurality of threaded holes can be arranged at equal intervals. In this way, when the support group 2 slides to a suitable position, a longitudinal baffle can be placed at the suitable position, and both ends of the longitudinal baffle are fixed to the transverse guide rail by screws or bolts to prevent the support group 2 from sliding and position it. The screw or bolt passes through the longitudinal baffle and is screwed into the threaded hole at an appropriate position on the transverse guide rail to connect and fix the longitudinal baffle and the transverse guide rail. The longitudinal baffle is vertically connected to the transverse guide rail. The threaded connection is convenient for disassembly and installation, so as to flexibly adjust the fixed position of the support group 2.

[0073] In an embodiment of the present application, the longitudinal guide rail includes two channel steels with concave surfaces facing each other and a steel plate connected between the two channel steels, as Figure 1 shown. The lower end of the sliding platform 5 can slide in the middle groove of the longitudinal guide rail, that is, on the upper surface of the middle steel plate. Further, a plurality of threaded holes are provided on the upper surface of each channel steel along the length direction of the longitudinal guide rail, and the plurality of threaded holes can be arranged at equal intervals. In this way, when the sliding platform 5 slides to a suitable position, screws or bolts can be screwed into both ends of the sliding platform 5 to fix the sliding platform 5 to the longitudinal guide rail to prevent the sliding platform 5 from sliding and position it. The screw or bolt passes through the sliding platform 5 and is screwed into the threaded hole at an appropriate position on the longitudinal guide rail to connect and fix the sliding platform 5 and the longitudinal guide rail. The threaded connection is convenient for disassembly and installation, so as to flexibly adjust the fixed position of the sliding platform 5.

[0074] In an embodiment of the present application, the prefabricated rolling welder further includes at least two longitudinal aggregate racks 15. The at least two brackets are connected with the longitudinal aggregate racks 15. The longitudinal aggregate rack 15 includes a longitudinal cross bar 151, a transverse cross bar 152, and a vertical stop bar 153. One end of the longitudinal cross bar 151 is connected to the upper side of the outer diagonal brace 205, and one end of the vertical stop bar 153 is connected to the lower side of the outer diagonal brace 205. Both ends of the transverse cross bar 152 are respectively connected to the longitudinal cross bar 151 and the vertical stop bar 153. The transverse cross bar 152 is used to support and place the reinforcing bars to be welded, such as Figure 1 , Figure 3 , Figure 5 as shown. By setting the longitudinal aggregate rack 15, multiple main reinforcing bars to be welded can be temporarily stored on the longitudinal aggregate rack 15, which is beneficial to the subsequent rapid welding with the auxiliary processing channel steel ring 14.
